Image

Jazz Pharmaceuticals focuses on oncology (lung cancer) and neuroscience and is traded around 7x MC/rev and 16x MC/FCF. They have multiple FDA approved drugs for narcolepsie and oncology with approx. patent expiration in 2030. The cash flow looks stable and they have done stock buybacks at around 100/share however revenue is declining. They have a good cash position but also much debt. They have couple of phase 3 trials that have to succeed otherwise they face a challenging time since their current drugs arent that profitable.

PD

It is a parental anti-tumour agent with potential activity against a wide range of tumours. Structurally it is a synthetic tetrahydroisoquinoline that is related to the marine ecteinascidins. Like trabectedin, lurbinectedin binds to the minor groove of DNA. Stable lurbinectedin-DNA adducts induce DNA double- and single-strand breaks which cause cell cycle arrest and ultimately, apoptotic cell death. It inhibits active transcription and the DNA repair machinery in tumour cells.
